api.setEnvironment call required before use. No mention in docs.

var api = new HydrogenProtonApi.AuthApi();

There is no mention in the docs of needing to do.
api.setEnvironment("https://api.hydrogenplatform.com")

before making calls like api.createUsingPostClientCredentials()

but if you don't, this.tokenUrl is null when the callApi function runs
var request = superagent(httpMethod, this.tokenUrl + path);

which leads to a dns error because the hostname can't be resolved.
